I have a Fritz!Box 7530, supplied by my ISP, and until now I have used its wifi provision to meet my needs. But a recent OS update means it now doesn't so I'm looking at alternatives. I'm fairly ignorant about wifi so I'd welcome suggestions. I'm somewhat paranoid about being attacked from the wider Internet, and in particular about attacks on wifi IOT devices (i.e. their firmware) which then lead to further attacks on the rest of my systems from the IOT devices. So I like to do two things: (1) keep my wifi devices on a separate subnet than my main wired network (2) prevent my wifi devices from accessing the Internet, where possible The 7530 assists with goal (1) by having a guest wifi network that uses a different subnet from the main wired network and 'main' wifi network. So I put all my wifi devices on the guest network and don't use the 'main' wifi network. Until recently the 7530 also assisted with goal (2) by allowing me to assign different 'profiles' to different devices on the guest wifi network. So my mobile phones do have permission to access the Internet, but most other devices (smart plugs, cameras etc) do not. But a recent OS update removed this ability. Now all devices on the guest network have to use the same profile. (it seems that existing devices keep the profiles they had, but new ones all get the same). I've talked to AVM but they won't fix the regression and I've talked to my ISP who say there's nothing they can do. So now I'm considering possibilities. The favourite at the moment is to buy another device (router? AP? I don't know what its called) that Ican wire into my main network and can establish a new wifi network that I can control better, and move all my devices to that. But I don't know what devices will allow me to do that, or which is best? Help! Please.
